Fitbug1 - With some injuries you can just about nurse yourself around a marathon course but I'm afraid achilles tendonitis in its acute phase isn't one of them.
A little test for you. Can you lift yourself up onto tiptoes just on the bad foot? If you can't it will need some serious rehabilitation.
You need to get that injury iced and rested. Symptoms can vary between people but this injury can last for a few weeks or a few months. I had it for 15 months before finally getting rid of it.
If the achilles area is badly swollen you should not attempt to run on it. If not swollen careful short runs of very low intensity on smooth and flat surfaces might be possible. Do no downhill running.
Shoes can be the problem. Have you been doing a lot of hard downhill work? Even on the level some shoes have a high heel tab at the back which digs into the achilles tendon and causes it to get irritated. This is my main theory for why AT happens. My advice would be to change shoes to ones that have a lower heel tab. With the existing shoes there are a couple of things you can do. You could cut the v-notch in the heel tab lower with a knife. You could also put heel inserts (e,g, sorbothane) under the footbed to raise the heel a little. Doing either or both of these will cause your shoe not to dig in at the same place.
Inserts are not a good long term solution, but may get you round.
Calf stretching is certainly very important but if you are at the beginning, very painful stage it may not be possible.
Give us an update from time to time and I'll see if I can come up with anything helpful.
